OpenTTD on a raspberry PI

I tried to play with the original Transport Tycoon back in the 90's on a 286 machine. Well it required a better video card than what I had so it didn't happen :(. I was stuck with Rome, Prince of Persia, UGH, Prehistorik and the likes :).
As of writing this it's a really nice experience to see these oldschool games actually had colours. Back then we had a grayscale CRT so I've never realized that.

So back on track with the PI and OpenTTD:
First I've grabbed the source code for the stable version from the official homepage:
You can choose if you would like to run the stable or the testing version of the game. Or if you like to live dangerously you can even try building a bleeding edge version (I'd advise you against it..). As long as you have the very same version running on the server (PI) and on the clients: you are good to go.

Then you need to install the build dependencies as instructed in their wiki page
